Wrap methods preserving arity.
npm install adhereWrap methods preserving arity.
The adhere method allows you to define a function factory that wraps a user
function, but preserving the airty of the wrapped function.
``javascript
var switcharoo = function (method) {
return adhere(method, function (object, vargs) {
vargs.reverse()
method.apply(object, vargs)
})
}
var reversed = switcharoo(function (a, b) { return [ a, b ] })
assert.deepEqual(reversed(1, 2), [ 2, 1 ], 'reversed')
``
This airty preservation has been extracted from
Cadence. This function builder is used to
preserve airty in Pointcut.
